Preparation method and application of collapsible loess curing agent
The invention relates to the technical field of curing agents, and discloses a preparation method and application of a collapsible loess curing agent, polyamide macromolecular chains are extremely easy to dissolve in water, amido, hydroxyl and the like in the structure of the polyamide macromolecular chains can coordinate with calcium and magnesium in loess, adjacent soil particles are mutually lapped through the macromolecular chains which are mutually crossed, wound, connected and condensed, and the collapsible loess curing agent is formed. Meanwhile, sulfonate radicals can react with components in soil, so that particles are cemented, the structure is strengthened, and the whole soil body becomes an integral firm spatial network structure; after the sepiolite absorbs water, the volume is expanded to generate certain strength, so that the compressive strength of the loess is favorably improved; the aluminum silicate cellulose is high in compression strength and good in toughness, can compactly fill a large number of pores of loess, reduces the porosity of the loess, improves the impermeability to water and has excellent heat preservation and frost resistance, harmless recycling of industrial waste residues is effectively achieved through the use of the inorganic filler, the doping amount is small, and the practicability is high.
本发明涉及固化剂技术领域，且公开了一种湿陷性黄土固化剂制备方法及其应用，聚酰胺高分子链极易溶于水，其结构中酰胺基和羟基等能与黄土中的钙、镁配位，将相邻的土颗粒通过互相交叉缠绕联结凝聚的高分子链相互搭接，同时磺酸根可与土中成分反应，从而胶结颗粒，强化结构，使整个土体成为一个整体性的牢固空间网络结构；海泡石吸水后体积膨胀会产生一定的强度，有助于黄土抗压强度的提升；硅酸铝纤维素耐压强度高，韧性好，可致密地填充黄土大量的孔隙，降低了黄土的孔隙率，改善了对水的抗渗性，具备优良的保温抗冻性能，无极填料的使用有效实现了工业废渣的无害化再利用，掺杂量少，可实施性强。
